I have been using my P4P for 3 years, without any issues.

When I turned it on today, suddenly these weird whirly noises appeared.

Its like something inside cannot rotate the way its supposed to, maybe like a broken fan...

Any ideas?

Hello there Emilian Dechev. I am sorry to read and to know that you are having this issue with your DJI Phantom 4 Pro and thank you for reaching out. May we know before this issue happened, was there a hard landing or a crash that happened to your DJI Phantom 4 Pro and are you receiving any error messages on the DJI Go 4 application? Thank you.

Thanks for the help

No, there was no hard crash, there were no error messages.
What parts of the Phantom are moving / rotating inside the shell, while on standby ?

Would it be a stiff fan that needs some cleaning?
